0033370: Foundation Classes - Moving into STL and Boost functionality

NCollection containers update:
  - NCollection_Array1 - updated functionality
  - NCollection_Array2 - NCollection_Array1 as a wrapper for 2array
  - NCollection_Vector -> NCollection_DynamicArray was renamed and reworked.
TCollection:
  - Use static empty string to avoid allocations on empty string
 NCollection allocators update:
  - NCollection_Allocator - allocator that used Standard::Allocate
  - NCollection_OccAllocator - allocator-wrapper that used OCC BaseAllocator objects
  - NCollection_IncAllocator - rework to increase performance
Standard:
  - Rework functionality to use different allocation libs
  - Implement basic of new way to wrap allocations tools
  - Define 4 ways to allocation (defines in configure stage)
 Additional changes:
  - Hash function uses std::hash functionality
   - size_t as a hash value
  - New HashUtils with Murmur and FVN hash algo for x32 and x64
  - Deprecated _0.cxx and .gxx DE classes reorganized
  - Create own utility for std memory
  - Update Standard_Transient to be more platform-independent
 Math TK changes:
  - math_Vector -> match_BaseVector<>
    - Buffer decreased to cash 32 elements instead of 512
